  Life-history: 
  A 
  female 
  of 
  the 
  grey 
  form 
  deposited 
  a 
  batch 
  of 
  

   S 
  eggs, 
  Dec. 
  28, 
  1905. 
  They 
  were 
  inserted 
  in 
  soil, 
  in 
  a 
  cylindrical 
  

   mass 
  about 
  12 
  mm. 
  long 
  by 
  4 
  mm. 
  in 
  diameter, 
  held 
  together 
  by 
  

   a 
  yellowish 
  brown, 
  dried 
  frothy 
  material. 
  The 
  eggs 
  are 
  4 
  mm. 
  

   long 
  by 
  1 
  mm. 
  thick, 
  cylindrical 
  with 
  rounded 
  ends, 
  finely 
  reti- 
  

   culated, 
  and 
  of 
  a 
  dull 
  testaceous 
  color. 
  One 
  female 
  under 
  ob- 
  

   servation 
  deposited 
  four 
  clusters 
  of 
  27, 
  28, 
  36 
  and 
  38 
  eggs 
  respec- 
  

   tively. 
  Of 
  the 
  first 
  lot 
  of 
  these, 
  the 
  first 
  egg 
  to 
  hatch 
  was 
  Feb. 
  

   13th; 
  four 
  more 
  hatched 
  Feb. 
  15th, 
  giving 
  47-49 
  days 
  for 
  the 
  

   egg-stage. 
  Three 
  of 
  these 
  were 
  reared 
  to 
  maturity. 
  Observa- 
  

   tions 
  were 
  interrupted 
  so 
  that 
  the 
  time 
  of 
  all 
  the 
  molts 
  was 
  not 
  

   observed, 
  but 
  their 
  number 
  was 
  determined 
  by 
  the 
  counting 
  of 
  

   exuviae 
  in 
  the 
  breeding 
  jar: 
  five 
  times 
  for 
  the 
  males 
  and 
  six 
  times 
  

   for 
  a 
  female. 
  The 
  period 
  between 
  molts 
  has 
  been 
  observed 
  to 
  

   range 
  from 
  10 
  to 
  20 
  days. 
  

  

  The 
  freshly-hatched 
  nymphs 
  were 
  5 
  mm. 
  ; 
  green, 
  dotted 
  and 
  

   marked 
  with 
  white 
  ; 
  anterior 
  and 
  intermediate 
  legs 
  grey-spotted. 
  

   (In 
  subsequent 
  lots 
  of 
  37 
  and 
  14 
  freshly-hatched 
  nymphs, 
  all 
  were 
  

   of 
  this 
  same 
  coloration). 
  The 
  first 
  molt 
  occurred 
  after 
  17 
  days, 
  

   and 
  then 
  the 
  n3^mphs 
  were 
  green, 
  the 
  anterior 
  and 
  intermediate 
  

   legs 
  green 
  like 
  the 
  posterior 
  ones. 
  They 
  remained 
  green 
  thruout 
  

   their 
  subsequent 
  stages. 
  Two 
  matured 
  to 
  green 
  males, 
  May 
  24 
  

   and 
  May 
  25 
  respectively; 
  and 
  one 
  matured 
  to 
  a 
  green 
  female, 
  

   June 
  6. 
  This 
  gives 
  about 
  100 
  days 
  for 
  the 
  nymphal 
  period 
  of 
  

   the 
  male, 
  and 
  about 
  112 
  days 
  for 
  the 
  female. 
  This 
  may 
  be 
  longer 
  

   than 
  it 
  would 
  have 
  been 
  in 
  a 
  state 
  of 
  nature; 
  as 
  the 
  conditions 
  

   of 
  the 
  breeding 
  jar 
  may 
  not 
  have 
  been 
  at 
  all 
  times 
  the 
  most 
  fav- 
  

   orable 
  for 
  growth 
  and 
  development. 
  The 
  egg-stage 
  plus 
  the 
  

   nymphal 
  stage 
  gives 
  about 
  five 
  months 
  from 
  egg 
  to 
  maturity.
